Use 'and' instead of &. & is a bitwise logical AND - it operates on the individual bits of its arguments. 'and' treats the full operand as a logical value. The results can be different:
 >>> [1] & [2]
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: unsupported operand type(s) for &: 'list' and 'list'
 >>> [1] and [2]
[2]
 >>> 2 & 1
0
 >>> 2 and 1
1
